Well I'm not sure how to check the current memory settings but I sure know how to adjust them :)
Presuming that you downloaded Tomcat directly and installed manually: open "$TOMCAT/bin/catalina.sh" Add the following somewhere near the top (I place mine after all the explanatory comments): JAVA_OPTS=" -Xmx1024m" This is tells java to allow a maximum of 1024 megabytes of memory to this instance of tomcat. Adjust appropriately. Please note: * the leading SPACE before the "-Xmx". * this is not a labeled parameter, therefore no "=" btwn the option and value.
